    Study Notes

    Network Basics

    • The main function of a network is to connect devices and facilitate communication between them.

    Types of Networks

    • A LAN (Local Area Network) connects a small number of systems in a relatively close geographical area.
    • The Internet is commonly referred to as a WAN (Wide Area Network) that spans a large geographical area.
    • A MAN (Metropolitan Area Network) connects several LANs in a metropolitan area.
    • WAN (Wide Area Network) typically spans a large geographical area, such as a city or country.

    Internet Characteristics

    • The Internet's main protocol suite is TCP/IP, which enables linking various types of electric devices worldwide.
    • The Internet's primary characteristic is its ability to connect devices and allow communication between them.

    Communication System Components

    • An input transducer converts input data into a signal that can be transmitted.
    • The receiver receives the signal and converts it back into the original data.
    • The transmitter sends the signal to the receiver.
    • The information source provides the data to be transmitted.
    • The channel provides a physical connection between the transmitter and receiver.
    • The destination receives the transmitted data.

    Data Transmission Modes

    • Half-duplex mode allows data transmission in both directions, but not simultaneously.
    • Simplex mode allows data transmission in one direction only.
    • Full-duplex mode allows data transmission in both directions simultaneously.

    Network Characteristics

    • A broadcast network provides a capability where several receiving stations can be reached simultaneously from a single transmitter.
    • The Internet is a network of networks, connecting multiple networks and devices worldwide.

    Key Concepts

    • The basic elements of a communication system are the information source, transmitter, channel, receiver, and destination.
    • The basic components of a communication system are the input transducer, transmitter, channel, receiver, and destination.
    • The main difference between a LAN and a MAN is the geographical area they span, with LANs covering a smaller area and MANs covering a larger area.
